[0002] Currently, most airport passenger boarding stairs docking platforms and sliding stairs are welded into a single structure, which is convenient in production and processes. A search revealed Chinese patent CN201999203U, which discloses a utility model patent entitled "Aircraft Passenger Staircase Platform." This patent includes a platform and a gangway, characterized in that the protruding end of the platform is detachably connected to the head of the gangway. The protruding end of the platform and the head of the gangway are connected by at least two fasteners, totaling four. The platform and the gangway are also connected by pins, one end of which extends into the platform, and the other end is fixedly connected to the gangway. The shortcomings of the above patents are: First, when passengers board the plane, the platform needs to bear the weight of the passengers and itself, resulting in a large force on the platform. The platform lacks support and is only connected to the gangway by a few fasteners, making the platform unstable and prone to shaking. Second, in the above patents, the platform and gangway need to be aligned before they can be fixed with fasteners. However, both the platform and gangway are large and heavy, making operation inconvenient, alignment difficult, time-consuming and labor-intensive. Summary of the Invention
